Folks, we need to talk about this Vitamin D trial. I have no stake in this game - take Vitamin D if you want but this pre-print is super sus.

The paper is presented as a randomized trial of vitamin D supplementation in hospitalized patients with COVID. Interesting and important question! And the results appear dramatic:
If true, this would be one of (if not THE most) effective treatments for COVID. But there are problems...
The first clue something is up is that the randomized groups aren't the same size:
It took me a while to figure out why this was, then I saw in the text that INDIVIDUALS were not randomized, WARDS in the hospital were.
OK - 8 wards, 5 randomized to Vitamin D, 3 to usual care. (Why not 4 and 4?? - but whatever). So this is actually a CLUSTER-randomized trial. That means you need to use CLUSTERED statistics to analyze it. They do not.
This is a big problem. But there is more. It seems that, even if the wards were randomized, the PATIENTS weren't randomized to the wards.
In other words, some hospital wards take different patients than others (different risk factors, etc). This is why we see this really weird finding in Table 1:
Baseline vitamin D levels dramatically lower in the "non-treated" group. Why? Preseumaby because different types of people got admitted to the wards than were randomized to usual care.
You'd expect people with low levels of Vitamin D to do worse - that has been shown multiple times - perhaps because higher Vitamin D levels are associated with less comorbidities.
Here's their Kaplan-Meier curve. It doesn't make sense. What do they mean by 'cumulative hazard' of mortality? What units are these? The overall mortality was 10% by their report.
I get frustrated with peer-review too, but this is why it's so important. This is super basic stuff - you don't call your study a randomized trial when it's a cluster randomized trial. And peer-reviewers would 100% have asked them to go back and redo the stats.
The authors could solve this, btw, by releasing a de-identified dataset (including the ward number) for this study. We could analyze it in about an hour at least for topline results using appropriate stats.
And again, is there harm from Vitamin D? Minimal honestly. The harm from promotion of studies like this is tweets like this that try to dissuade people from getting vaccinated and doing other protective measures.

So please, read skeptically. Pre-prints have been a boon in COVID times but this study is just... not well done. Be aware. (/END)

Before we get too far into 2021, I thought I’d write a thread recapping some of the research that came out of my lab in 2020. Most of this work was led by my talented team of graduate students, Kerrianne Morrison, @kmdebrabander, and @DesiRJones.

Back in January, a news story was published about Kerrianne’s study showing improved social interaction outcomes for autistic adults when paired with another autistic partner.

A detailed thread about the study and a link to the paper can be found here (feel free to DM me your email address if you’d like a copy of the full paper for this study or any of our studies):


Another paper published early in 2020 (it appeared a few months earlier online) showed that traditional standalone tasks of social cognition are less predictive of functional and social skills among autistic adults than commonly assumed in autism research.


Next, @kmdebrabander led and published an innovative study about how well autistic and non-autistic adults can predict their own cognitive and social cognitive performance.

In medicine, reckoning with racism includes reappraising the very syntax we use every day. Proud to add my voice w/ @J_Ikeme and @RWGrantMD in this @JAMAInternMed pub addressing:

Does race/ethnicity belong in the first line of the patient

Some background: I’ve struggled with this question since early in medical school

Medical syntax is designed to communicate information in a predictable sequence with key elements prioritized to facilitate efficient communication and formation of an assessment and plan

2/

From preclinical lectures to Qbank questions to clerkship rotations, race/ethnicity was often prioritized in the same sentence as age + gender.

I grew accustomed to reading/hearing: a 70-year-old Black man w/ history of x, a 50-year-old Hispanic woman presented w/ y.

3/

However, when it came time for me to use race/ethnicity, there was always tension. Race/ethnicity are self/socially-ascribed identities that in clinical practice are almost always assumed by providers based on appearance. I was also concerned about the potential for bias

4/

I wondered how my own care would be impacted or not impacted by my ethnicity (Hispanic) – I have light skin so I’m not sure if my doctors would even identify me as such – but how would my care be different if I was presented as a 30-year-old Hispanic male?

5/

ADHD, a thread (1)
If you have #ADHD & are struggling please know you’re not alone. This week on @Overview, we're talking about living w/ ADHD & Anxiety during the pandemic & many the stigmas & misconceptions that making things worse.

I was diagnosed w/ ADHD when I was 7. And in so many ways it’s been a blessing. I love my energy, the hyper-focus, the calm I feel in chaos, the ability to & feel emotions so intensely. It’s allowed me to to see the world differently be in a constant state of wonder.(2)

But realizing all that has been a long, difficult journey so figured I’d share some of my own struggles as well as the resources from @HowtoADHD because Jessica's channel has been a game-changer for me.(3)

First off, #ADHD Attention Deficit Hyperactivity Disorder is a dumb description. It implies a deficit in attention & always hyper people. ADHD is a spectrum, & what we all have in common isn’t that we can’t pay attention. It’s that we have trouble controlling our attention.(4)

There are amazing analogies out there, like trying to watch 6 TV’s at once when someone else controls the remote. Or like driving a race car on city streets and spinning out whenever you try to turn.

Me: Made a thread about how people don't understand hyperacusis and give advice that obviously I've already tried.

This person only a few tweets into the thread:


I only tweeted this because, like it or not, this is the general population's reaction to me talking about hyperacusis.

Similar replies happened when there was the whole "not clapping" article regarding Cambridge.

They're so quick to label disabilities as not real disabilities.

It's important to remember this when people may ask why we've never talked about this before, or why it's not talked about a lot.

Most people don't talk about their hyperacusis because if they do, people respond like this. So most of the time, honestly it's easier to say nothing

Yes I am petty enough to add screenshots of this toxicity to this thread:


Asking for accessibility is "pathetic." /s : )

Some thoughts on this: Firstly, it might be personal preference, but I am not keen on this kind of campaign as I feel like it trivialises cancer. Sometimes the serious message gets lost because people are sharing pics of cats or whatever and the important context is gone.


More importantly, the statistic being used in the campaign is misleading. It says 57% of women put off cervical screening if they can't get waxed. But on further investigation, that's not accurate.

The page here goes on to say "57% of women who regularly have their pubic hair professionally removed would put off attending their cervical screening appointment if they hadn’t been able to visit a beauty salon."

So the 57% represents a concern not across the whole population of women, but only those who regularly get waxed. So how big of an issue is this across the whole population? And what else is stopping people getting smears?

I think campaigns for cancer screening are really tricky because there is so much nuance that often doesn't fit into a catchy headline or hashtag. It's certainly not easy and is part of a bigger conversation.

SRI KANTESH HANUMANTHA, KADARAMANDALAGI (KAR)
#bharatmandir

KANTESHA means Prabhu full of brightness.
Here, Sri Hanuman appears with a front face and sparkling eyes. Earlier, the village was also called KANTESHPURI on the name of Kantesha Hanuman.


Several thousands of years ago, Hanuman lived in this village. He once saw the Sun and mistaking it to be a fruit, began flying towards it. Since then, this village came to be known as Kadara Man Dalagi. (Kadar means rays, mandala is cluster of rays).


It is believed that King Janmejaya had set up the shrine to get rid of his difficulties.
There is a small pond on the right side of the kshetram where Teppotsava (Float festival) is celebrated.

Kanaka Dasa has praised Sri Kantesha in his various poetic compositions.


Kanaka Dasa was the first devotee to popularize the power of Kantesha. It is said that once Kanaka Dasa was deeply wounded in a battle. To seek blessings, he visited Tirupati but Sri Venkatesha appeared in his dream and advised him to see Kantesha first before seeing him.

Keep dwelling on this:
Further Examination of the Motif near PRRA Reveals Close Structural Similarity to the SEB Superantigen as well as Sequence Similarities to Neurotoxins and a Viral SAg.

The insertion PRRA together with 7 sequentially preceding residues & succeeding R685 (conserved in β-CoVs) form a motif, Y674QTQTNSPRRAR685, homologous to those of neurotoxins from Ophiophagus (cobra) and Bungarus genera, as well as neurotoxin-like regions from three RABV strains

(20) (Fig. 2D). We further noticed that the same segment bears close similarity to the HIV-1 glycoprotein gp120 SAg motif F164 to V174.

Statue of Equality (Ramanuja) Muchintal, Hyderabad, Telangana

The Statue of Equality is a monument in India dedicated to the 11th-century Vaishnavaite Sage Bhagavad Ramanuja, commemorating 1000 years since his birth. It was inaugurated by Prime Minister Narendra Modi ji in 2019.


In 2014, Sri Chinna Jeeyar came up with the idea to commemorate the 1000th anniversary of Sri Ramanuja's teachings by building the Statue of Equality. The statue is constructed on an estimated 34 acres in Hyderabad, India.


It consists of a 216 foot tall statue of Ramanuja and is surrounded by 108 Divyadesams (model temples) and includes an educational gallery. The project budget is 1000 crore rupees.The foundation stone for the Statue of Equality was laid by Chinna Jeeyar.


The statue was built by Aerosun Corporation in China before being shipped to India. It is made of panchaloha, a combination of gold, silver, copper, brass and titanium. The statue relies on donations to fund its construction.


The temple is located on the 27,870 square metre second floor with a 120 kg statue of Ramanuja, representing the years he lived, meant for daily worship. The 1,365 square metre third floor including a Vedic digital library and research center.

fascinated by this man, mario cortellucci, and his outsized influence on ontario and GTA politics. cortellucci, who lives in vaughan and ran as a far-right candidate for the italian senate back in 2018 - is a major ford donor...


his name might sound familiar because the new cortellucci vaughan hospital at mackenzie health, the one doug ford has been touting lately as a covid-centric facility, is named after him and his family

but his name also pops up in a LOT of other ford projects. for instance - he controls the long term lease on big parts of toronto's portlands... where doug ford once proposed building an nfl stadium and monorail... https://t.co/weOMJ51bVF


cortellucci, who is a developer, also owns a large chunk of the greenbelt. doug ford's desire to develop the greenbelt has been

and late last year he rolled back the mandate of conservation authorities there, prompting the resignations of several members of the greenbelt advisory

Read through a forum thread on Chastity Mansion to see who is talking about the Edge-o-Matic and figure out what more to address regarding frequent questions, as well as scout out user feedback. Here's some thoughts you can carry back to the forums!

My website doesn't have any product reviews, but people scatter them everywhere else in forums, tweets, xtube vids, etc.

If you ARE a previous customer, and you like the thing, can you drop a review on my site to help others?

The price is steep, but that's the amount of coins I calculated to make these. I have several spreadsheets calculating every expense involved with this project.

The current cost sustains production and development of new tech, and is helping create jobs. We are 2 people now!!

It IS 3D printed, because injection molding is orders of magnitude more expensive for the initial tooling, and I am still making small revisions to the enclosures.

Injection molded plastics are a six thousand dollar commitment for fifteen cent parts. Great for mass mfg.

Also, if you didn't know, 3D printing technology allows for some shapes which would be difficult, expensive, or impossible on injection molding or milled parts!!

Undercuts, which I use in this design, require special lifters to mold that cost a tremendous fortune.
